the power supply. In this case, both RF function and (U)SIM card will be invalid.
AT+CFUN=4 can set the module into airplane mode. In this case, RF function will be
invalid.
In this mode, the current consumption of the module will be reduced to the minimal level.
During this mode, the module can still receive paging message, SMS, voice call and
